Whenever the sun flashed off the metallic finish on the bottom of Joe McKnight's shoes, anyone behind him caught a hefty amount of glare.

Saturday during USC's first practice of the season, plenty of Trojan defenders got a good look at the shiny cleats as they scampered away.

McKnight ripped off three long runs on the day, and showed USC coaches and fans exactly what he could do if his body was right.

"I'm glad to be back. I feel super healthy. I'm feeling like Superman," McKnight said. "I feel good being a 100 percent finally. I just want to take full advantage of it, take care of my body and keep going like this - keep making plays."
